Voltage controlled current source inverters

Proceedings of the 1992 International Conference on Industrial Electronics, Control, Instrumentation, and Automation, 2003
The authors present a fully functional voltage controlled current source inverter (VC-CSI) three-phase inverter that can closely track a given voltage reference signal and also provide various performance improvements. The adaptive SPWM control method has been used to force the output voltage to track the respective sinusoidal reference signals.

Improved voltage regulation for current-source inverters

IEEE Transactions on Industry Applications, 2001
Voltage regulation schemes for current-source inverters (CSIs) commonly use a simple proportional-integral (PI) stationary frame controller, but this approach is known to suffer from significant steady-state error. In contrast, the more advanced schemes that are routinely used for current regulation of voltage-source inverters (VSIs) avoid these ...

Predictive current control of voltage source inverters

IECON'01. 27th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.37243), 2002
A new current controller for a voltage source inverter based on calculation of an electromotive force is presented in this paper. Practical aspects of realizing the new controller in a system with a signal processor are considered. Delays introduced by measurements are taken into consideration.

A hybrid, current-source/voltage-source power inverter circuit

IEEE Transactions on Power Electronics, 2001
A combination of a large current-source inverter and a small voltage-source inverter circuits is analyzed. The resultant hybrid inverter inherits certain operating advantages from both the constituent converters. In comparison with the popular voltage-source inverter, these advantages include reduced switching losses, improved quality of output current

Voltage source inverter

2015 International Conference on Energy Systems and Applications, 2015
In this paper, the different types of voltage sourse inverters are studied. The voltage source inverters are the main component of the variable frequency drives(VFD). In the medium voltage variable speed drive market, the various techniques have progressed with constituents, design, and reliability.

Instantaneous voltage measurement in PWM voltage source inverters

2007 International Aegean Conference on Electrical Machines and Power Electronics, 2007
The use of pulse width modulated (PWM) inverters is nearly universal in industrial drives, making accurate voltage measurements problematic due to the switching nature of the applied phase voltage. Often, the applied phase voltage is reconstructed by using a combination of the DC link voltage and the commanded PWM duty cycle.

Voltage source inverters for high-power, variable-voltage DC power sources

IEE Proceedings - Generation, Transmission and Distribution, 2001
The paper discusses the applications of voltage source inverter (VSI) based power electronic systems for interfacing variable-voltage DC sources to the grid. A variable-speed wind power conversion system is used for illustration, where the VSI-based interface needs to convert a variable DC voltage to a nearly constant AC voltage with high-quality power.

Harmonics in voltage-source PWM inverters

International Journal of Electronics, 1981
he performance of an induction motor fed by PWM inverters is mainly determined by the harmonic contents of the output voltage. This paper presents a method of numerically calculating the harmonics in the output voltage waveform. Equal pulse-width modulation and siunsoidal PWM are studied.
